Like, if you open a french book, mark a word and click "definition", does any definition in french pop up? Has anyone had any good or bad experience with those dictionaries? (admitting they are there)

Could anyone with a kobo touch confirm/deny this?

I have a 2.0.0 kobo touch since a couple of days and when i read french books i have access to the french dictionnary (just tap and hold a word and it comes up). Odd thing is that sometimes it sets itself to english and i have to tinker a bit with it.
